Product Details


    The QHY PoleMaster eliminates the frustrating aspects that can happen during polar alignment. Save time with this highly sensitive camera! You can start polar aligning before the night sky becomes truly dark with its high sensitivity.

    Simply mount your camera to the front of your RA axis, it will then capture an image of the northern sky and then calculate where true north is based on that image. The information is displayed on a screen, helping you make any slight adjustments if needed.

    QHY PoleMaster EQ Mount Polar Alignment Camera-box

    The QHY PoleMaster is the perfect accessory for your system

    Check out its features:

    Accuracy:Your best polar alignment can now be achieved in the order of a maximum 30-arcsecond range.

    Wide-angle view: Its wide field-of-view (11 x 8 degrees) makes it very easy to locate the pole star. 

    Easy to install:Easily install it onto any equatorial mount through mount-specific adapters, even on mounts without a polar scope.

    Real-time monitoring and adjusting: You can monitor your polar alignment in real-time. If polar alignment is lost, it is now a simple matter to bring it back without having to start from scratch.

    Three-star alignment no longer needed: Once you are polar aligned, you will only need to perform a one-star alignment - a real time saver.

    Pair it with a single axis mount: When used with a single (RA-only) axis mount, good polar alignment will minimize drift in the DEC axis, therefore maximizing the performance of your mount.

Beware Windows 10 Users

The first night it worked fine plugged into a 2020 Dell XPS 17. The next night I got to experience the lag nightmare that is all over the internet and noted in other reviews here. The thing freezes up for sometimes a few seconds and sometimes 30 seconds. This makes it totally unusable. What is worse it that this appears to have been an issue for years and QHY does nothing about it. Their response, as parroted on many websites, is to play a video in the background. This appears to help sometimes but is a bizarre and completely unacceptable workaround even if it worked 100% of the time. Some people blame power management of the USB ports. While it appears that Win10 by default gives itself the tyrannical power to turn off power to the ports, even after I disable that option in Device Manager the problem persists. QHY needs to fix this problem and OPT/others should push them to do do or at least warn Win 10 folks that this is a potential deal killer. To almost make it worse, this morning the camera/software works fine in my living room. So, is this how it will be, it works fine when not needed and craps out when there are clear skies?

Eye Saver

I'm in a rural area, but the neighbors love their bright lights. This makes it difficult to spot Polaris in the scope of my Skyguider Pro. Along with the Pole master universal adapter and a Manfrotto tripod adapter I'm able to get a spot on polar alignment without the acrobatics and eyestrain. I like that it works with my phone, so no need for a laptop.

QHY PoleMaster EQ Mount Polar Alignment Camera

In my opinion it is an essential product for those of us in the southern hemisphere with medium light pollution; since the alignment by Octans is almost impossible due to its low magnitude of light.

Great product

The Polemaster is great but when I bought it I asked which adapter for my mount. I'm using the lx85 and was told to get the universal adapter. It doesn't work for the lx85. Good thing I'm a machinist and made one that works.
